Analysis pipeline for each condition. Photo steerable pyramid: Pipeline for the original model from Roth et al.24. Line drawing steerable pyramid: Pipeline for Line drawing – Pyramid Filter condition. Instead of photographs of real-world scene images, the line drawings are used as inputs of the model. The line drawings were computer-generated using the MLV toolbox. Contour: Pipeline for Contour Orientation condition. The same line drawing images were vectorized. Then, the orientations of those contours were computed. The model and the figures are borrowed from Roth et al. Only four orientations were shown here for visualization purposes. The images presented here are solely for illustration purposes and were not part of the study’s dataset.
